Edit: syntaxcomplete.vim
" Vim completion script " Language: All languages, uses existing syntax highlighting rules " Maintainer: David Fishburn <dfishburn dot vim at gmail dot com> " Version: 13.0 " Last Change: 2013 May 14 " Usage: For detailed help, ":help ft-syntax-omni" " History " " Version 13.0 " - Extended the option omni_syntax_group_include_{filetype} " to accept a comma separated list of regex's rather than " string. For example, for the javascript filetype you could " use: " let g:omni_syntax_group_include_javascript = 'javascript\w\+,jquery\w\+' " - Some syntax files (perl.vim) use the match // syntax as a mechanism " to identify keywords. This update attempts to parse the " match syntax and pull out syntax items which are at least " 3 words or more. " " Version 12.0 " - It is possible to have '-' as part of iskeyword, when " checking for character ranges, tighten up the regex. " E688: More targets than List items. " " Version 11.0 " - Corrected which characters required escaping during " substitution calls. " " Version 10.0 " - Cycle through all the character ranges specified in the " iskeyword option and build a list of valid word separators. " Prior to this change, only actual characters were used, " where for example ASCII "45" == "-". If "45" were used " in iskeyword the hyphen would not be picked up. " This introduces a new option, since the character ranges " specified could be multibyte: " let g:omni_syntax_use_single_byte = 1 " - This by default will only allow single byte ASCII " characters to be added and an additional check to ensure " the charater is printable (see documentation for isprint). " " Version 9.0 " - Add the check for cpo. " " Version 8.0 " - Updated SyntaxCSyntaxGroupItems() " - Some additional syntax items were also allowed " on nextgroup= lines which were ignored by default. " Now these lines are processed independently. " " Version 7.0 " - Updated syntaxcomplete#OmniSyntaxList() " - Looking up the syntax groups defined from a syntax file " looked for only 1 format of {filetype}GroupName, but some " syntax writers use this format as well: " {b:current_syntax}GroupName " - OmniSyntaxList() will now check for both if the first " method does not find a match. " " Version 6.0 " - Added syntaxcomplete#OmniSyntaxList() " - Allows other plugins to use this for their own " purposes. " - It will return a List of all syntax items for the " syntax group name passed in. " - XPTemplate for SQL will use this function via the " sqlcomplete plugin to populate a Choose box. " " Version 5.0 " - Updated SyntaxCSyntaxGroupItems() " - When processing a list of syntax groups, the final group " was missed in function SyntaxCSyntaxGroupItems. " " Set completion with CTRL-X CTRL-O to autoloaded function.
